Maniraj Yadav — SDE-1 @ SwishX

01/Profile

Hey ✌ I'm Maniraj.

The performance side is what I enjoy most — goroutine fan-out, context cancellation, and knowing when a problem genuinely needs concurrency versus a better data model.

I'm a final-year Computer Science student at SRM University AP, currently an SDE-1 at SwishX in Bengaluru, where I build backend services for a pharma distribution platform. Much of my work is making requests that touch several services return fast — running independent calls concurrently so a response costs the slowest one instead of the sum of all of them, batching what would otherwise be hundreds of round trips, and making sure that when a request is cancelled, the work still in flight gets torn down with it.

I built a 6-level sales hierarchy engine on recursive PostgreSQL CTEs, automated an MOQ-based cashback flow that replaced a manual points-grant process across 90 schemes and 568 rules, and shipped a CMS backend in Go delivering 20+ REST APIs with Redis caching and S3 storage.

On the side: a RAG-based Git analyzer that answers questions about a repo's commit history, an AI resume builder, and a roommate-finding app. Oracle Certified Professional for Java SE 17, and an open-source contributor. Away from the screen I volunteer with NSS — blood donation camps and beach clean-ups, mostly.

SDE-1

Feb 2026 — Present

SwishX · Bengaluru, India

Backend engineering on a pharma distribution platform. Joined as a Software Developer Intern and was promoted to SDE-1 in Aug 2026.

▸Built a 6-level sales hierarchy engine using recursive PostgreSQL CTEs, enabling single-query subtree retrieval across 401 employees, 19,028+ retailers and 4,038+ stockists spanning 24 states and 10 divisions.
▸Automated MOQ-based cashback for retailers by integrating scheme evaluation into the wallet credit flow, replacing a manual points-grant process; supports 90 active schemes and 568 MOQ rules.
▸Deployed a production-ready CMS backend in Go using the Factory Pattern, delivering 20+ REST APIs across 3 product verticals with Redis caching and AWS S3 storage.
▸Researched and evaluated 5 fuzzy string matching algorithms for automated name reconciliation during KYC verification, significantly improving approval rates for 7,000+ users.

06/Architecture

Making a request cost the slowest call, not the sum

The pattern I reach for most at work. A request that needs data from several services used to run them one after another, so the response cost the total of every call. Fanning them out as goroutines and joining the results means it now costs only the slowest one — and a single cancelled request tears the whole tree down with it.

concurrent request fan-out

//errgroup: the first error cancels the siblings, so nothing waits on a result that is already useless

//ctx cancellation propagates -- a dropped request leaves no orphaned goroutines running

//Batched reads collapse hundreds of round trips into a handful

Let's build something that scales.

I'm open to backend and full-stack roles, and happy to talk through an interesting systems problem either way.
